I would really like insider insight on the last years of Steve Ballmer. A lot of the good things Microsoft is doing started under his last few years. Whether he deserves credit or not, is another story. I know Scott Guthrie gets a ton of credit from a lot of people for turning the company around, especially with Azure & Open Source.
I'm also curious what really happened with the Nokia debacle. Microsoft had some die hard phone fans & many people wish they could have one that ran Android apps but with the MS Phone UI so they could have the best of all worlds.
